Some things you simply have to trust. If you can hack into the server, change an image and make sure it is not noticed, you would hardly need a keylogger anyway.
I'm pretty sure the admins had some elaborate security mechanisms in place to prevent tampering with the images, e.g. read-only media, cryptographic sums stored at a different server, etc.
I would almost trust those computers more than my own desktop at home.
The Eindhoven University of Technology (tue.nl) reinstalled the entire operating system (win9x) of all public computers from an image every day at first boot. Also, any user could choose to do the same thing at any time. Just reboot, and choose to reinstall. The systems were completely open, you could install anything you wanted, so I used to do it everytime, just to be sure I was working on a clean system.
This was about 5 years ago, since then, every student has his own laptop, so I guess the public computers are gone...
And checkout will be very easy. Instead of scanning every item by hand, a reader can quickly tally every item in your cart. Not to mentioneEvery cart could have a reader that keeps a running tally for you. No more overspending.
This has actually been tried already (around 1998/9, I believe). Just fill your cart, drive it through a gate, and it displays how much you have to pay...
I don't think the products had unique ID's though, only the product types. So there were some problems trying to figure out how many items of 1 product type were in the cart.

Pendulums, at least the last delay (I only watched the last part, it's kind of boring...)
The pendulum just circles around, in smaller circles until it hits a domino, et voila!
A Boeing 767 has a maximum fuel capacity of about 24000 US gallons. See

I speak and read Dutch, English and German, and if I try really hard, I can read a bit of French.
En natuurlijk ook nog het plaatselijk dialect (ik woon in (Nederlands-)Limburg).
